EA has released a free-to-play first-person shooter called "Duty Calls", which is an obvious parody of Activision's premier franchise, Call of Duty. The game has been developed to try and promote their upcoming, over-the-top shooter, Bulletstorm.
Duty Calls claims it's "the most epically epic game of all time" and has a fully playable five-minute long campaign.
Some of the highlights of the game are: Duty Vision, which slows down the action so you can fire more bullets; immersive dialogue; cold, calculated realism and more.
You can download the game from its official website: Duty Calls: Official Website.
